The day before the tsunami struck.

On the airliner to the Maldai Islands, Xingyu woke up from his sleep. Looking at the flight route map on the seatback screen, Xingyu found that the plane was already approaching the periphery of the Maldai Islands. Xingyu, who was sitting next to the window, hurriedly turned sideways and looked down at the sea from the window. Nervous anticipation of the beautiful scenery 'three-color sea ring' that I have heard since childhood. Xingyu's parents both love to travel, and the two of them were backpackers in their early years, and they like to travel freely with backpacks on their backs. And Xingyu also inherited his parents' preferences, he doesn't have a girlfriend, and he likes to travel alone with a backpack.

The Maldai Islands are the place where Xingyu's parents fell in love. Although after getting married, they still often travel to various places. But Xingyu's mother is obsessed with the Maldai Islands. One of the most memorable scenery for Xingyu's mother is the three-color sea ring. The waters of the Maldai Islands are crystal clear, and the bottom of the sea is covered with fine sand of coral grinding by the waves. This allows the sea surface of Maldai to reflect the brightness of the sun. The water near the beach is light blue, the middle layer is blue, and the outer part is dark blue. Looking down at the island from above, it looks like Saturn surrounded by tricolor rings. Xingyu has heard this scene countless times since he was a child, so he is especially looking forward to it.

Just as Xingyu was looking at the window with great interest, a girl sitting next door asked, "Are you okay?" Look at you and you've been lying on the window since you woke up. Do you want me to call the flight attendant for you? ”

"I'm fine, I'm just looking at the scenery on the sea." Xingyu replied as he turned to look at the girl. Xingyu fell asleep on the plane. For this trip, Xingyu, who is in his third year, has been working two summer jobs. I haven't had a good night's sleep in the past few weeks. So after getting on the plane, he was relaxed, and naturally fell asleep quickly. At that time, no one was sitting in the next seat, so he naturally wanted to see the girl talking. Xingyu's eyes lit up, the girl was about one or two years younger than Xingyu, and the girl with short hair and melon seed face was beautiful and cute.

After listening to Xingyu's answer, the girl frowned and continued to ask: "We are in the sky above the Indian Ocean!" During the whole flight, only the blue sky and white clouds were seen outside, and the sea came and went below, why did you look so energetic? After Xingyu heard the girl's inquiry, he replied with a smile: "It's about to go to the Madei Islands." The island is beautiful with a tricolor ring. Many people only know that the sea view of Madai is beautiful, but they don't know that there is another scenery when they see Madai from a high altitude. Then Xingyu explained to the girl what a three-color sea ring is. As a result, after hearing this, the girl also leaned on the window with great interest. Fortunately, Xingyu's seat has two windows, one is next to Xingyu's head, and the other is in front. Girls are not afraid of strangers lying on the front window and looking down. As a result, the number of people lying on the window of the machine has changed from one to two.

"My name is Mia, a sophomore at XX University. This time I went on a trip to Maldives with my parents. The girl seemed to open the conversation box and continued: "But we didn't set off together, my parents were on a business trip in the United States." They will arrive in Madai tomorrow evening. ”

"It turned out to be a school girl! I'm also in XX University, but I'm a junior. Xingyu, who usually doesn't talk much, also began to chat while looking forward to the beautiful scenery because of Mia's cheerful personality who is not afraid of unfamiliar characters.

"Look over there! See, it's really beautiful! Mia shouted excitedly as Heungwoo looked in the direction she was pointing.

The beauty of the three-color sea ring far exceeds Xingyu's expectations, and it is even more beautiful than Xingyu imagined. In Xingyu's imagination, there is only one small island with a set of three-color sea rings. However, Maldives is an archipelago of many small islands. The distance between the islands and the islets is not far. Therefore, from the plane, the small islands on the sea surface form a natural pattern around the sea rings.
